ABSTRACT:
The present invention relates to a power supply system which can provide a dual air flow control and heat reduction in an electronic device having a regular fan. The power supply system has an additional backup fan operating independently from the regular fan and further comprises a thermal control circuit comprising a solid state temperature sensor for detecting ambient temperature changes inside the electronic device and a fan power drive electrically connected to the solid state temperature sensor as well as to the backup fan to turn on or off the backup fan in response to ambient temperature changes. The power supply system also comprises a pair of resistors connected respectively to the solid state temperature sensor to set a low and a high trigger temperatures based that the backup fan is able to make a proper response to ambient temperature changes provided, however, that the high trigger temperature shall be higher than the low trigger temperature.
